A dult spinal deformity (ASD) surgery remains technically challenging and is associated with high rates of complications, one of which is pseudarthrosis. 8–11 , 22 , 27 The rates of pseudarthrosis in ASD have ranged from 0% to 35%, 5 , 8–10 with one comprehensive review citing pseudarthrosis as the most frequent long-term complication of those studied, reporting a rate of 7.6%. 27 Patients who develop pseudarthrosis are at risk for instrumentation failure and may require revision surgery. Risk factors for pseudarthrosis have been studied and include

T he incidence of scoliosis in the elderly has been reported to be from 30% to 68%. 25 , 27 Surgical treatment for adult spinal deformity (ASD) is associated with high complication rates. 16 , 17 , 35 A recent study found that approximately 27% of patients with ASD experience at least one medical complication perioperatively. 33 High perioperative complication rates have been reported in elderly patients (aged 65 years or older) surgically treated for ASD and range from 37% to 71%. 1 , 10 , 30 , 32 A large proportion of the morbidity in the elderly is caused

T here has been a sharp spike in the number of adult spinal deformity (ASD) surgeries performed in the US over the past decade ( https://hcup-us.ahrq.gov/overview.jsp ). Compared with some of the most prevalent chronic diseases such as diabetes, congestive heart failure, or chronic lung disease, ASD has been shown to have a significantly greater impact on health-related quality of life (HRQOL) and higher cost of treatment. 17 , 23 This increased burden of ASD places substantial pressure on the scientific community to better delineate treatment effectiveness in

I t is well recognized that many developed countries, including the United States, are experiencing an unprecedented demographic shift toward an older population. As the ranks of the elderly grow, it will be increasingly important to appreciate and address their health care needs. Although the prevalence of adult spinal deformity (ASD) has been estimated to range from 2% to 32% in the general population, 7 , 10 , 21 , 35 , 38 its prevalence has been estimated to be as high as 68% among the elderly. 41 The finding of spinal deformity in many adults may be

Degeneration via XLIF Jody A. Rodgers , MD, FACS (Spine Midwest, Inc.); W.B. Rodgers , MD , and Edward J. Gerber 3 2011 30 3 A22 A22 2011 Introduction: The XLIF approach provides a minimally disruptive alternative to anterior column access that allows for large graft placement, disk height restoration, and indirect decompression, while avoiding posterior scar tissue from the previous procedure. Results of ASD treated with XLIF are presented. Methods: Of our single-site consecutive series of 932 XLIF patients, 276

adjacent segment disease (ASD) in the cervical spine. Methods: 888 patients received ACDFs for symptomatic degenerative disease of the cervical spine over the past 22 years at our institution. Of these, 108 patients received repeat ACDF surgeries due to symptomatic ASD. 77 received revision surgeries anteriorly, and 31 received posterior surgeries. Pre, intra, peri, and post-operative data were collected via clinical notes and patient interviews. Patients were followed up for an average of 111.8±76.5 months after the first ACDF. Results: In general, patients
